The groundwater level in Zanjanrood catchment area, with a cold semi-arid climate, has been severely declined over the recent years as a result of population growth, groundwater over-extraction and, the recent droughts. Therefore, determining the groundwater potential zoning map for the area is of importance for supplying demand water and a proper water efficiency. In this research, we used seven effective criteria for groundwater potential assessment. The analytical hierarchical analysis process was used for weighting the criteria. Overlay analysis in the ArcGIS was implemented using Topsis model to prepare the groundwater potential map in four different classes of priority of the groundwater potential. To clarify the model results we used the geoelectrical investigations (Resistivity and IP) across the two different priorities determined using the Topsis model.
